Autonomic Dysreflexia with Elevated Diastolic Only?

I don't have the answer to your specific question. However, I have a few recollections from my time in the hospital. When I was first injured, my AD was quite severe. Something as little as leg spasms when I was put in bed good caused my blood pressure to rise to a level that caused head-splitting headache within seconds. Both systolic and diastolic were elevated. The systolic seemed to reduce fairly quickly, but the diastolic stayed elevated much longer, and that seemed to maintain the headache. I wonder if in your case the systolic is already reduced but this diastolic is still staying at an elevated For a while longer.

Or than eight years later, I am relieved to find that I rarely get severe headaches as I did initially. Also, my blood pressure does not spike very quickly these days. Nevertheless, I ensure that I always have with me blood pressure reducing medication, including prazosin, captopril, and nifedipine.
